In the absence of LPS, the WEs from the 'heating foods', litchi, longan, or dried longan had a dose-dependent enhancing effect on PGE2 production, with respective EC50s of 8.4, 16, and 11 mg/ml.
      
Foods traditionally regarded as 'heating' (litchi, longan, and dried longan) or 'cooling' (chrysanthemum flower, bitter gourd, and lotus seed plumule) were extracted sequentially with water and ethyl acetate.
      
The absolute stereochemistry of5 was determined by its chiral synthesis from L-allylglycine, proving that5 is the C-4 epimer of the amino acid previously isolated from dried longan seeds.
      
The SSRs studied produced 22 different patterns, allowing the unambiguous identification of 16 lychee and the 4 longan cultivars studied.

In order to solve the problem of Cuscuta europaea endangering woods, fruit trees and medicinal plants etc, the author made the test and research on the Euphoria longan and Aleuites fordii parasilized by C, europaea.The effec is noticeable by using a new wide-ranging herbicide (Glyphosate). The C.europaeaan cbe killed radically.So we consider Glyphosate as the finest chemicals in controlling C.europaea.In this article, the author also gives the detailed description of materials, methods and the result of...
